Assume federal exemption is, $3300.00, you earn. 37,500.00, the tax rate is 2 3/4%, calculate the tax.

Sauron [17]

3300 exemption

37,500−3,300=34,200 taxable
Tax rate is
2+3/4=2.75% we don't multiply 2by 3/4
Now calculate the amount of tax
34,200×2.75%=940.5

Point M is the midpoint of segment JK. Find JK when JM=6x-7 and MK=2x+3.

Whitepunk [10]

If M is the midpoint of JK then JM+MK=JK and JM=MK
so
6x-7=2x+3
minus 2x both sides
4x-7=3
add 7 both sides
4x=10
divide both sides by 4
$x=\frac{10}{4}$
$x=\frac{5}{2}$

sub back

JM=6x-7
$JM=6(\frac{5}{2})-7$
$JM=\frac{30}{2}-7$
$JM=15-7$
JM=8

JM=MK=8
JM+MK=8+8=16=JK

$x=\frac{5}{2}$ and JM=8=MK and JK=16

the equation of a given progressive wave is

y=5sin(100πt−0.4πx) ......(i)

The standard equation of a progressive wave is

y=asin(ωt−Kx) ...(ii)

Comparing (i) and (ii), we get
